The present invention is directed generally to tools that are lightweight, high quality, durable, rigid and strong. For example, various tools used to level items and/or as a straight edge for aligning or drawing lines on items may be designed in an improved or augmented beam style so that they are lightweight, strong, durable and rigid so as to hold their shape under stress or return to their original shape after being stressed. In various exemplary embodiments, the beam style level and/or straight edge may have a first main elongated side to which two elongated perpendicular sides are connected or coupled. At least one or more higher strength elongated sides, for example a second elongate side, may be comprised of a closed or triangular shaped side. For example, the second elongated side may be, for example, a triangular shaped construction.
